Some handy software tools
Below are a few handy tools created and coded by members of the chainmaille community. Most of them are still being developed and have a few quirks which I'm trying to document as I find to help the usability, none the less they are some neat tools.
Canvas IGP paints an image onto a virtual piece of chainmail. Great for patterns and inlays.
The AR calculator figures out roughly how many rings of a given size it takes to build a 1 by 1 foot sheet of European 4 in 1 along with an approximate weight of the completed piece.
This calculator is used when you know what AR you want, but you're not sure what size of wire or the inner diameter of ring you that you need.
